Symbolic Expressions of Composite Grid Structures

摘要

In summary, graphs and s-expressions are really different manifestations of thesame entities. While graphs are visual, they nonetheless possess dual representations in the textual s-expression alphabet. As a result, LISP, which is based entirely on s-expressions, is an ideal language for dealing with applications that perform extensive manipulations on graph-based objects. Scientific applications which make extensive use of both graph based objects as well as traditional numerical arrays can benefit by implementing their higher level data and control structures in LISP. Segments of code that are computationally intensive can be written in a static language such as C or FORTRAN and linked in with the higher level code. Such a design strategy could preserve the benefits of static compilation (i,e,. faster execution speed) while retaining the power and flexibility needed to manipulate complex data structures.
